tips from the karma sutra.

Auddalika says, `Females do not emit as males do. The males simply remove their desire, while the females, from their consciousness of desire, feel a certain kind of pleasure, which gives them satisfaction, but it is impossible for them to tell you what kind of pleasure they feel. The fact from which this becomes evident is, that males, when engaged in coition, cease of themselves after emission, and are satisfied, but it is not so with females.'
This opinion is however objected to on the grounds that, if a male be a long-timed, the female loves him the more, but if he be short-timed, she is dissatisfied with him. And this circumstance, some say, would prove that the female emits also.
ON KISSING
IT is said by some that there is no fixed time or order between the embrace, the kiss, and the pressing or scratching with the nails or fingers, but that all these things should be done generally before sexual union takes place, while striking and making the various sounds generally takes place at the time of the union. Vatsyayana, however, thinks that anything may take place at any time, for love does not care for time or order.
On the occasion of the first congress, kissing and the other things mentioned above should be done moderately, they should not be continued for a long time, and should be done alternately. On subsequent occasions, however, the reverse of all this may take place, and moderation will not be necessary, they may continue for a long time, and, for the purpose of kindling love, they may be all done at the same time.
The following are the places for kissing: the forehead, the eyes, the cheeks, the throat, the bosom, the breasts, the lips, and the interior of the mouth. Moreover the people of the Lat country kiss also on the following places: the joints of the thighs, the arms and the navel. But Vatsyayana thinks that though kissing is practised by these people in the above places on account of the intensity of their love, and the customs of their country, it is not fit to be practised by all.
Now in a case of a young girl there are three sorts of kisses:
The nominal kiss
The throbbing kiss
The touching kiss
When a girl only touches the mouth of her lover with her own, but does not herself do anything, it is called the `nominal kiss'.
When a girl, setting aside her bashfulness a little, wishes to touch the lip that is pressed into her mouth, and with that object moves her lower lip, but not the upper one, it is called the `throbbing kiss'.
When a girl touches her lover's lip with her tongue, and having shut her eyes, places her hands on those of her lover, it is called the `touching kiss'.
Other authors describe four other kinds of kisses:
The straight kiss
The bent kiss
The turned kiss
The pressed kiss
When the lips of two lovers are brought into direct contact with each other, it is called a `straight kiss'.
When the heads of two lovers are bent towards each other, and when so bent, kissing takes place, it is called a `bent kiss'.
When one of them turns up the face of the other by holding the head and chin, and then kissing, it is called a `turned kiss'.
Lastly when the lower lip is pressed with much force, it is called a `pressed kiss'.
There is also a fifth kind of kiss called the `greatly pressed kiss', which is effected by taking hold of the lower lip between two fingers, and then, after touching it with the tongue, pressing it with great force with the lip.
As regards kissing, a wager may be laid as to which will get hold of the lips of the other first. If the woman loses, she should pretend to cry, should keep her lover off by shaking her hands, and turn away from him and dispute with him saying, `let another wager be laid'. If she loses this a second time, she should appear doubly distressed, and when her lover is off his guard or asleep, she should get hold of his lower lip, and hold it in her teeth, so that it should not slip away, and then she should laugh, make a loud noise,
WHEN love becomes intense, pressing with the nails or scratching the body with them is practised, and it is done on the following occasions: on the first visit; at the time of setting out on a journey; on the return from a journey; at the time when an angry lover is reconciled; and lastly when the woman is intoxicated.
But pressing with the nails is not a usual thing except with those who are intensely passionate, i.e. full of passion. It is employed, together with biting, by those to whom the practice is agreeable.
